摘要:
近年来随着城市建设用地的不断扩展，城市生态环境问题越来越突出，因此，进行建设用地扩展对地表特征参数的影响研究显得十分重要。以重庆都市区为研究对象，采用1988，2000，2011年 LandsatTM遥感数据和1∶50 000DEM数据，基于人机交互解译和定量遥感技术相结合的方法，提取了土地利用现状数据和三个地表特征参数：地表温度、NDVI、土壤湿度，并分析建设用地扩展对地表特征参数的影响。研究结果表明：从1988—2011年，重庆都市区建设用地主要向西部和北部扩展，地表温度中的高温区主要向北迁移，NDVI和土壤湿度在建设用地扩展的区域呈下降趋势；城市建设用地扩展与地表特征参数的变化趋势呈现出明显的相关性，其中，建设用地的扩展与热环境呈正相关且在扩展方向具有高度的一致性，与NDVI和土壤湿度呈负相关关系。研究成果旨在为改善城市地表热环境效应、优化城市生态环境提供科学依据与参考。
Abstract:
Along with the urban construction land expanded in recent years, Urban ecological environment has been becoming an outstanding problem. Therefore, the study on the construction land expansion effects on surface characteristic parameter is very important. This paper took the main urban district of Chongqing as research site. By using 1988, 2000, 1988 LandsatTM 1∶50 000 DEM data and remote sensing data, and based on the method of man-machine interactive interpretation and the technology of quantitative remote sense, the data of land use status and three surface characteristic parameters—land surface temperature, NDVI, soil moisture were obtained, and the influence of the urban construction land expansion characteristic parameters on the surface was analyzed.The results show that: from the 1988—2011, the construction land of the main urban district of Chongqing was mainly expand to the west and north, the high surface temperature has mainly migrated towards to north, NDVI and soil moisture in the area of construction land expansion declined; correlation bwtween the urban construction land expansion and the change trend of surface characteristic parameters was obvious, the positive correlation between thermal environment was significant, and the expansion of construction land was highly consistent with the extension direction, and the relationship between NDVI, soil moisture and the expansion of construction land was negatively correlated. The results can provide the scientific basis and reference for improving urban surface thermal environment effect, optimize the urban ecological environment.
